JAKARTA, Oct. 16 (Xinhua) -- More earthquakes would occur with stronger magnitude in the next 30 years in Indonesia's West Sumatra province, where a 7.9 magnitude quake killed more than 1,000 people and left thousands of others missing last month, the Kompas.com reported here on Friday.

"We estimate that the magnitude would reach around 8.8, or 0.1 less than that," Kery Shieh, head of Singaporean Earth Conservatory, was cited by the website as saying.

At a recent presentation delivered in Nanyang University of Technology, Singapore, Kerry said the incoming quakes could take longer time than 4.5 seconds on September 30 in West Sumatra. "The quake could last more than 5 minutes."

Kerry is working with a team that has been studying the quake phenomenon in West Sumatra province.

Citing the results of earthquake history and geological study in West Sumatra, Kerry said that the deadly earthquake on September 30 was only the beginning.

Kerry said that the latest earthquakes in the area failed to reduce and 'taming', the enormous energy from the earth plates movement far under the ground that would gradually be released within the next 30 years through earthquakes.
